There are many types of coronavirus. Some get you a cold. The coronavirus that the 2019-2022 pandemic is causing a disease called COVID-19.
A virus infects your frame by entering healthy cells. There, the invader makes copies of himself and multiplies your frame.
The coronavirus blocks its bristly surface proteins at receptors on healthy cells, especially those in the lungs.
Specifically, viral proteins enter the ACE2 receptors of cells. Once inside, the coronavirus hijacks healthy cells and takes over. Eventually, it kills some of the healthy cells. However, there is evidence that the Omicron variant does not attack lung tissue as much as other variants.
COVID-19, the disease caused by the coronavirus, begins with droplets from an inflamed person’s cough, sneeze, or breathing. They may be in the air or on a surface you touch before touching your eyes, nose, or mouth. This gives the virus a passage to the mucous membranes of your throat. Within 2 to 14 days, your immune formula would possibly react with symptoms such as:
The virus travels through your respiratory tract. It is the airway that includes the mouth, nose, throat, and lungs. Your lower airway has more ACE2 receptors than the rest of your airways. COVID-19 is more likely to pass than viruses like the common cold.
Your lungs may become inflamed, forcing you to breathe. This can lead to pneumonia, an infection of the tiny air sacs (called alveoli) inside your lungs where blood exchanges oxygen and carbon dioxide.
If your doctor performs a CT scan of your chest, you’ll most likely see shadows or asymmetrical spaces called “ground-glass opacity. “
For most people, symptoms end with cough and fever. More than 8 out of 10 cases are mild. But for some, the infection becomes more serious. About five to eight days after the onset of symptoms, they experience shortness of breath (called dyspnea). Acute respiratory distress syndrome (ARDS) begins a few days later.
ARDS can cause immediate breathing, immediate central frequency, dizziness, and sweating. It damages the tissues and blood vessels in the alveoli, causing waste to accumulate inside. This makes breathing more difficult, if not impossible.
Many other people with ARDS need help breathing with a device called a ventilator.
As fluid builds up in the lungs, they bring less oxygen into the blood. This means that the blood may not supply enough oxygen to the organs to survive. This can cause the kidneys, lungs, and liver to close and stop.
Not everyone with COVID-19 has these serious complications. And not everyone wants medical care. Some studies even suggest that the Omicron variant might not be as severe in the lungs as other variants. .
Some other people also have symptoms, including:
Researchers have reported mouth sores and rashes, adding purple-red spots on the hands or toes.
In general, young people are not as ill health from the coronavirus as adults, but they can become inflamed and it can also be fatal for them. Some young people and adolescents have been admitted to hospital with an inflammatory syndrome that can be similar to coronavirus. Symptoms come with fever, rash, abdominal pain, vomiting, diarrhea, and problems in the center. The syndrome, now called multisystem inflammatory syndrome in children (MIS-C), is similar to poisonous surprise or Kawasaki disease, a condition in children that reasons inflammation of the blood vessels. We are still learning about those cases.
The long-term effects of COVID-19 on its framework are still unclear. Some patients have so-called “long journeys” in which they suffer symptoms for weeks or even months.
